How to access modules up a directory [PLEASE HELP!]

[InTheProcess]

I have been trying to look this up, but there is no tutorial other than LOVES Wiki. In the wiki, it stated that I can change the "require()" function's directory by using "love.filesystem.setRequiredPath(path)". I have no idea what the default value means. Here it is for reference. "?.lua;?/init.lua."

you can use the ... vararg in the main body of a file you're requiring to get a path you can manipulate, and use that to go up a directory... IF it's not already the one where
- your main.lua is, or
- it is the root of your save folder

You don't need to mess with setRequirePath.

What do you mean by “vararg”. The closest thing I can think of is “Variable Arguments”. I need a cement ration please.

Srry, lol. I need a demonstration

was gonna ask what you meant by that, but thanks for the clarification

Yes, i do mean the variable argument that lua has, the ellipse (...)

Here's an example:

Code: Select all

-- bar/foo.lua

local path = ... -- this is in the file scope, and when requiring this file, it'll contain the require path it was found through

print(path)


-- main.lua

local meh = require "bar.foo"

After you have that path, some string manipulation to cut off the end to some extent is needed; in some libraries it is done that way, i just can't remember the exact solution to that; at that point, you can have just the directory of the required file, and from that, you can have the directory above it... but only if it wasn't already on the same level as main.lua since you can't go above that.

I am pretty confused. I am pretty new to lua and love2d. Here is my situation. I have "state.lua" control my gamestates. One of those is the menu. In the menu script, I have to access a library for the menu gui. Here is a picture of my file structure. I want a kind of a tutorial. I just don't understand why some things are the way they are. Maybe show it in action.

I need help understanding it

[ReFreezed]

Is there a reason you don't want to use full paths, i.e. require("data.scripts.lib.gui.button")?

[InTheProcess]

Oh, I didn't realize that was an option. Thanks, I got it from here.

I did go on the assumption that you wanted to access a directory that was "above" where your main.lua was; since it's not, paths starting from that folder will work, as said by Refreezed.
